Rumor has it the honeymoon is over between Lindsay Lohan, Samantha Ronson and lesbianism!

OK! Magazine is reporting that sometimes Lindsay feels like a nut, and sometimes she's don't. Since we're not talking about candy bars here, that probably doesn't sit well with her girlfriend - Samantha.

On August 5 at the Delano Hotel’s Florida Room, Lindsay, 22, cozied up to other men whenever Sam left her side.

“Lindsay was laughing and giggling with these guys,” an eyewitness tells OK!.

And earlier that day, guests at the Miami hotel witnessed the couple’s repeated clashes.

“Lindsay is the aggressive one in the relationship,” an insider tells OK!. “Sam tries to focus on Lindsay, but it’s never enough.” Another friend adds, “Lindsay has to be the center of attention, or she’ll flirt with other guys to make Sam jealous.”

But back in L.A. on Aug. 6, the pair were “hand in hand and very affectionate” at Crown Bar, and on Aug. 8, they partied for Sam’s birthday.

I'd love to see Lindsay and Sam make it for a while, but from the looks of things that ain't gonna happen.

I'm starting to believe that Lindsay Lohan is just a sex addict.
